vTo all whom it may concern:

Be it known lthat l, GUsrAvUs H. MAR- QUARDT, e citizen of the United States, residing et Cnssville, in the county of Barry end Stfite of Missouri, lieve `invented `certain new and useful Improvements in Gesolene- Engines, of which the following is e speciiicstion. l v

lily invention hes relation to new end use'- ful improvements in gesolene engines, and it is so designed that the same action occurs in eech end of the cylinder; thus there will be an impulse for every stroke, two impulses for every revolution, exce t when the engine is over speeding, the fue supply being cut oii' by a governor designed for that purpose.

lt will readily be deduced from the above that the engine consists of but one piston end one cylinder.

. The inein object of my invention is to pro duce an engine oi' the type referred to that will oper-ete on the seme principles es that el steam engine, its smoothness of operetion being due to the fact that the manner in weich the cylinder is designed gives the pis.- ton e Hdouble action which kee s up e'- steedy uninterm ted movement oi the fly wheel of the engine. lt is obvious that en engine of this type should have a number el' advantages over one having e. single action cylinder, seine of which ere inthe nature of simplicity of construction, ns s. lesser ernennt of nieeliinery is required to develop the seme ernennt oi power, other edventeges heing economy, smoothness of operation, etc.

lt is observed tliet an engine of niy construction should he adapted for ell classes of work.

Although gasolenc is perferehly used es e. fuel in the oeration of my engine, other 5u ls, adapten Vor the purpose, such es emile oil` elcohol, or their equivelents, reey he employed.

Another edvntege my device lies over others is that it may loe used either es e vertieni or horizontal engine.

With these and other objects in view, my

' invention oonsists of the novel construction end erre 1 ment olf perte es are liereinefter described 1n the following specification, illusin the eccompenying drewings form.- n part thereof, and particularly point ed ont the claims hereunto eppended.
